Paper is a renewable source, while burning coal to heat water to steam to turn turbines to create electricity to run one of those hand dryers, is not renewable.
Hi, i am a mechanical engineer and i have made some audits about the subject.
Actually it is better to use the hand blower. Although paper is a renewable source (it can only be recycled a few times) much energy from oil is used in it's production (i.e. cut trees, transport to factory, energy used in the factory, transport to warehouse, transport to supermarket, plastic to put the paper in, etc). It is much better to use the hand blower because you are saving a lot of emissions in the transport of the energy (electricity). And if you have solar panels to use with the hand blower the better.

Perhaps they could save paper by not having a paper dispenser in the first place. Why not use a hand blower instead?

Why did they color the paper? Seems that should be harmful in some way too.

Why did not use the USA map?

Evidently, paper only comes from one country...
